I created a list of memory modules that community (here or Framework Forum) reported working with Framework 13 AMD.
Hope this helps.

For now, I’m planning to buy either G.SKILL F5-5600S4040A32GX2-RS if the price is good enough, or Micron Crucial CT2K32G56C46S5.
I just got mine as well!
Got shipment notification 16:00 yesterday, got it 11:30 today.
